Operation in winter

First read and observe the introductory information and safety warn-
ings on page 164.
At low temperatures, the vehicle battery only has part of the initial power output
that it has at normal temperatures.
A discharged vehicle battery may already freeze at temperatures just below 0
°C.
We therefore recommend that you have the battery checked by a specialist ga-
rage before the start of winter, and recharged if necessary.
Charging a vehicle battery

First read and observe the introductory information and safety warn-
ings on page 164.
A properly charged vehicle battery is essential for reliably starting the engine.
›
Switch off the ignition and all of the electrical components.
›
Only for "quick-charging": Disconnect both battery cables (first of all "negative",
then "positive").
›
Attach the terminal clamps of the charger to the battery terminals (red = "posi-
tive", black = "negative").
›
Only now plug the mains cable of the charger into the power socket and switch
on the device.
›
When charging is completed: Switch off the charger and remove the mains ca-
ble from the power socket.
›
Only then disconnect the charger's terminal clamps.
›
Reconnect the cables to the battery, if necessary (first of all "positive", then
"negative").
It is not normally necessary to disconnect the cables of the battery if you re-
charge the vehicle battery using low amperages (as for example from a mini-
charger). Refer to the instructions of the charger manufacturer.
A charging current of 0.1 multiple of the total vehicle battery capacity (or lower)
must be used until full charging is achieved.
It is, however, necessary to disconnect both cables before charging the battery
with high amperages, so-called "quick-charging".
"Quick-charging" the vehicle battery is dangerous and requires a special charger
and specialist knowledge. We therefore recommend that vehicle batteries be
quick-charged by a specialist garage.
The vent plugs of the vehicle battery should not be opened for charging.
CAUTION
On vehicles with the START/STOP system, the pole terminal of the charger must
not be connected directly to the negative terminal of the vehicle battery, but only
to the engine earth » page 184, Jump-starting in vehicles with the START-STOP
system.
